Be it known. that Louis A. STEAUBEI.. a citizenI of the United. States,andresident of Green Bay? in the county of Brown tain new and usefulimprovements in Paper-Folding); Machines; and l do hereby (ieclarc that'the Foiiowing is a iuii, ciear, and. exact description. thcrsoi 10 Thisinvention relates to intesi-folding inan chinos and is particuiarlydirecteii to double, od, intciziifoiding machines which are adaphed toproduce packages of intcri'olded sheets of paper. l5 The primarypurpose' of this invention is to produce an interoiciing machins Whiciiwill hohl. the paper at each oid immediately a-L'L'ter the told has beenproduced, alici which 'will hold the central portionoif the 2c foldedpaper 'to prevent buiging or unfolding, thas adapting the machine 'tothe filing' oi" eren the thinnest kinds oi paper such as toilet paperfor instance.

in generai this invention is an improve- 25 ment over that disciosefi in.my United, States Patent Number 1,423,276 of July 18, 1922, forpaper'foldingi'nachines and hasthe sanne. geneliai objects as those sstiiorth in the shove noteo patent.lx in addition "so so the, speciicobjects enumerated; above.

Further objects src to provide an i.nter '.tfoidina; machine in whichseveral ho'iding oeps-esser- .iaps and tuching bia-(ies arc operated ina regnisr manner hy extremely simple, mechanism having Vsry 'few parts.,sncf; so formed`1 that 'ail or" the parts are rug vgsd and reishie sindare not likely to get ont of order. y hnrthsr objects are to provide aninific prot/eci. iorn of hoider plates for the folded paper which are soconstructed that the paper is securely hehi against shifting, even atthe time timing which the inici is maris, thus insuring the productionof, a package is oi' uniform Width although formed of inten iioldcciseparate sheets. 4

Furthsr objects ars to provide a machins for producing inter-foiciefisheets oi' this psper in which a` combination olif iong and 5o shortpresser flaps :is employed, the former to hoid the okied portion of thepaper ininieciiatciy after' ing and thc latter to hold :in intermediateportion of the Loioeci 'paper to prevent isengsgement of th@ inst im orloos@ Sh, and t0 'thus .keep such shect and.
